1. You have installed v.0.9.4. Please, update it to current v.0.9.5.
2. It seems that it's not related to mobile_pda template as webpage generation is stopped before loading template.

I installed new version few days ago to test if it helps, but its not. I forgot to back-up CSS files that's why restored recently back to 0.9.4.

With new version problem still exists.
What could be a reason to all that?

vbarkouski, I just sent you pre-release of v.0.9.6 - please test it.
